In the term of sedimentary features of Neopaleozoic in south of North China Basin, lateral variation of sedimentary facies was studied selectively in Benxi-Taiyuan Formation, Shanxi Formation, Lower Shihezi Formation, Upper Shihezi Formation and Shiqianfeng Formation. Lithofacies paleographic features and the sedimentary evolutionary process of Late Paleozoic in south of North China Basin were worked also.

根据华北盆地南部上古生界的沉积特点，按本溪组—太原组、山西组、下石盒子组、上石盒子组和石千峰组5个层组分别开展了沉积相的横向变化对比研究，并以此为基础探讨了华北盆地南部晚古生代的岩相古地理特征及其沉积演化过程。

The contents of total organic carbon and humic acid carbon in the soil from stone pit were markedly higher than that of the soils from rocky ditch, swallet or stone cavern.

结果表明：喀斯特石漠化区阔叶林土壤有机总碳含量和腐殖酸碳含量明显高于灌木林、灌草丛和稀疏草丛，而土壤水溶性有机碳含量的变化则相反；喀斯特森林退化后，土壤有机碳的累积量减少、流失量增加；喀斯特小生境土壤有机总碳和腐殖酸碳含量存在明显的水平空间变异：石坑＞石沟＞石缝＞石洞。

It is explained that the large fractionation of boron isotope observed in tourmalines of Altay No. 3 pegmatite is resulted from the fractionation of boron isotopes between tourmaline and muscovite, and also tetraborate, in combination with the fractionation between fluid and melt phases.

本次研究利用电气石-白云母和电气石-四硼酸盐矿物间的同位素分馏以及熔体相-流体相间的同位素分馏，合理解释了阿尔泰3号伟晶岩脉电气石B同位素分馏过程，并首次获得伟晶岩形成、演化过程中B同位素组成演化的全程图谱。

In northeastern of basin, together with the structural framework of slope belt and the dynamical information of well, we can conclude that the gas reservoir in Taiyuan-early Shihezi formation dominantly belong to protogene depositional gas reservoir under the normal pressure, and the gas favourable reservoir belt was controled by framwork of main sandbody; But in upper Shihezi Formation to Shiqianfeng Formation the gas reservoir show the feature of secondary Tectonic-depositional gas reservoir under the extremely low pressure, and the gas favourable reservoir belt mainly locate in a zone which the low amplitude structure and main sandbody superposed in the slope belt.

5盆地东北部斜坡带构造与钻井生产动态资料的相关分析结果表明，太原组-下石盒子组气藏主体属于正常压力下的原生岩性气藏，其有利含气区带主要受控于主砂体分布格局；上石盒子组-石千峰组气藏则主要为异常低压下的次生构造-岩性气藏，其有利含气区带主要分布在斜坡带低幅度构造与主砂体叠合区。

Basic status on waste rock pile s of an uranium mine in Jiangxi province before its decom- missioning is introduced.

According the analyse of orthogonal experiment content of fiber brucite and ratio of water/plaster will affect plaster mould"s most wetness break intension markedness and content of fiber brucite is mostly complication while ratio of water/plaster is subordination complication ;In the precondition of better fluidity , plaster mould"s most wetness break intension is on that content of fiber brucite is 3.6% ratio of water/plaster is 0.65,it become 2.96 Mpa which is increase 54.17% to no fiber brucite plaster moulds

根据正交实验结果，在保证石膏浆流动性的情况下水镁石纤维含量在3.6％，水膏比在0.65时标准石膏模型湿态抗折强度最大，达到2.96Mpa，比未添加水镁石纤维时的湿态抗折强度增加了54.17％，水镁石纤维含量在4.2％，水膏比为0.65时的干态抗折强度最大值达到6.92Mpa。

Its color can effect the beautiful decorative materials; black can be a touchstone; some can also be used jade. 2, in gemology, the corner stone with a limited angle word meaning rock, and sometimes also used to refer to Bristol stone or flint.3, angular stone, the middle finger in paleontology is a kind of fossil cephalopods name.

其色彩美丽者可作用装饰材料；黑色者可作试金石；有的也可用于玉雕。2、在宝石学中，角石一词具有不限于角岩的含义，有时也用于指碧石或燧石。3、角石，在古生物学中指的是一种头足类动物的化石名称。

The shapes of the stone tools gradually increased, such as stone hoes, millings, hammers, knives, axes, gravers and stone containers etc, and the shapes of stoneware grew steady.

石器的形状从旧石器时代的少数几种发展为石锄、石磨、石锤、石刀、石斧、雕刻器，以及石制容器等等，并且石器的形状也逐渐趋于定型。

The device group to fill a number of artificial stone blank mechanical projects, the quality of the arrival of European and American countries similar products standards, so the device can be processed into a satisfactory artificial stone plate, and their products are widely used in×,°×, artificial stone door process, laboratory facilities, sauna facilities, countertops, stair handrails, baseboard, desktop, hand-wash basins, bathtubs, wash-specific Units of children in kindergarten, medical-specific console, such as decorative profiles, but also can produce signs, ashtrays, tea sets, trays, boards, vases, candlesticks and other man-made stone crafts.

该设备组填补了多项人造石机械项目的空白，质量完全到达了欧美国家同类产品的标准，因此该设备能够加工出令人满意的人造石板材，其产品广泛应用于门套、窗套、人造石工艺门、实验室配套设施、桑拿浴室配套设施、台面、楼梯扶手、踢脚线、桌面、洗手盆、浴盆、幼儿园儿童专用洗漱台，医学专用操作台等装饰型材，同时也可以生产指示牌，烟灰缸，茶具，托盘，棋盘，花瓶，烛台等各类人造石工艺品。
